Public bug reported:
The Trusty HWE kernel from Xenial lacks the PCI ID for the Solarflare 8000
series NIC.
This prevents network installs on servers which only have that NIC.
In order to get NIC detected, link up, and successful network install,
only 2 commits are required:
dd248f1bc65b sfc: Add PCI ID for Solarflare 8000 series 10/40G NIC
93171b14a545 sfc: make TSO version a per-queue parameter
This patchset is undergoing testing, and I will post the patches to the
kernel-team mailing list.

There are some kernel messages produced possibly due to additional commits
missing,
but are benign/non-fatal and allows the NIC probing and basic functionality to
work.
[ 2.803941] sfc 0000:37:00.0 (unnamed net_device) (uninitialized):
Solarflare NIC detected
[ 2.806336] sfc 0000:37:00.0 (unnamed net_device) (uninitialized): Part
Number : SFN8042

command 0x4a inlen 8 failed rc=-2 (raw=2) arg=0
[ 2.808052] sfc 0000:37:00.0 (unnamed net_device) (uninitialized): no PTP
support
[ 2.808488] sfc 0000:37:00.0 (unnamed net_device) (uninitialized): MC
command 0x8f inlen 0 failed rc=-1 (raw=1) arg=0
[ 2.808605] sfc 0000:37:00.0 (unnamed net_device) (uninitialized): failed to
allocate PIO buffers (-1)
...
[ 4.037694] sfc 0000:37:00.0 p2p1: link up at 40000Mbps full-duplex (MTU
1500)
The PTP (precision time protocol / ieee 1588) support is a feature to
synchronize clocks
over a computer network with high precision, and is not required for basic
functionality
nor for this particular user.
The failure to allocate PIO buffers is non-fatal, see
sfc/ef10.c/efx_ef10_dimension_resources() comments.
The additional patches to resolve the error messages will be worked on
another SRU cycle.
